The Thermaltake Bigwater 760i is decent alternative to other inexpensive watercooling units. At about $150 USD it is about as affordable as a Swiftech or Danger Den basic kit and probably performs on a similar level. The entire unit is simple to install, though the process is rather lengthy. Everything is included in the kit so there is nothing else the user needs to buy to get started, although there are several add-on blocks and accessories available from Thermaltake that will work with this kit. In fact, there is a picture on the Thermaltake website showing the Bigwater 760i cooling two NVIDIA 8800 series video cards with two Thermaltake TMG ND4 coolers.

There were a few minor issues with the Bigwater 760i. The fan included with the system was one of the loudest fans in the test group, even when set to low speed. To make matters worse, the fan speed control know was mounted inside the case where it was not easily accessable to the user. There was plenty of room on the front panel to install the knob to the right of the mesh opening, which would allow the user to quiet down the fan when the maximum performance was not needed. One other issue was that the front bezel was not lined up correctly and allowed the silver frame of the unit to be exposed.

Overall the Bigwater 760i is a great way to start watercooling your system, or add a second loop to a watercooling system for additional blocks without sacrificing performance of the main loop.
